(If we ignore the fact that they can enter visa exempt...) Isn't it a very strange request from the embassy to ask the girlfriend for a domestic partnership certificate?! I mean you can't apply for touristvisa as a family (married or not), each person must apply individually so whether someone is married, single or living with a partner should be irrelevant... or am I missing something here? 🤔
no, your entry history does not reset because it is a new calendar year. As someone mentioned already, you are most likely "flagged" in their system as being warned and denied entry and you are likely to be denied one more time if you try after just 2 weeks.
studying thai language is not approved as ground for DTV in most embassies. I've seen a few cases where it was accepted, but many have been denied with the advice to apply for ED visa instead.
the application process is the same no matter if you have kids in school or not...
However you need to do some research about schools and check if any of them accept a child to study on a DTV... they are likely to requier an ED visa.
Start with school research for the area you want to stay in, before deciding and applying for any visa. (Check the costs and what visa that is needed.)
...on the application form you are supposed to add your intended departure date and a flight number (so one can just add a flight no of a flight you are planning to book). Just like the OP did.
However there have been a few posts where the embassy has asked for flight tickets as additional information. That is not the norm though.
Anonym deltagare you are contradicting yourself in your post and by this comment...
"...my boss didn't wanna sign the statement as I'm not going to be an employee when I'm a freelancer."
and
"I sent my current employment contract and I will be working remotely for my company."
Either you will work remotely as an employee of a company outside Thailand... Then a work contract is valid information to send and the work contract needs to mention that you are allowed to work remotely (this is what the embassy is asking for).
OR
You you apply as a freelancer with clients outside Thailand. I guess this is what you are going to do and that your current employer is going to be your future client.
If that is the case you need to write an explanation about this to the embassy. If you are ending the work contract you sent, then it is not really a "base for your application". For that you need to show client contracts (one or more if you have).
So you need to make a client contract with the company where you have worked up until now. (It could mention that you've previously been employed and that they will pay for your services as a freelancer going forward. It should include what type of work you will do for them etc.)
